It's been puffing a little steam on cold startup , indicating coolant in the combustion chamber(s) - a sweet taste in the tailpipe condensate gave it away . Got the right side head off today and what I thought was likely to be a head gasket seep wasn't . Turns out there's a crack between an intake and an exhaust valve - 4 valves per cylinder , 24 total V6 DOHC 3.4 . The crack is in the same cylinder that blew a spark plug out 3 0r 4 years ago . This is a 1999 , got 347,000 miles on it , and a set of heads runs around 1400-1800 bucks
- I'm not going to replace "just what's broke right now" . Between the heads and all the other parts needed (~$3,000 total), the SUV just isn't worth the cost of repairs to us . And that's with me doing all the mechanickin' , if we were paying a shop it would be another 2 to 3 grand . While the motor would have a new top end , the rest of the vehicle will still have 347k miles on it . And who knows what will fail next ? Nickel and dimin' is one thing , but when the repairs run a couple thousand at a whack ...
